Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current phospholipid processing methods, particularly the hydration method, face challenges such as low acetone insoluble content, requirement for chemical bleaching, and difficulty in separating inactivated phospholipids and water-soluble impurities, leading to poor emulsification and reduced nutritional value of phospholipid products.
Innovation Solution
A phospholipid processing aid is produced by hydrolyzing soybean oil sediments, creating a yellow-brown powdery solid that is water-soluble but n-hexane-insoluble, which is used to form high-purity active phospholipid lamellar liquid crystals, enhancing surface activity and emulsification properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the hydration method is used to prepare concentrated phospholipids by dehydrating soybean oil sediments, then the production process is simple, but the acetone insoluble content is low (60-65 g/100 g) and chemical bleaching is required
Solution Approach 1:
The patent changes the water content parameter in the hydration method from conventional low levels (24-74% of soybean oil sediment weight) to a specific range of 30-50% of soybean oil sediment weight. This parameter optimization enables simultaneous achievement of high acetone insoluble content (95-98 g/100 g) and simplified production processes without requiring chemical bleaching
Solution Approach 2:
The patent creates a new processing approach that copies the simplicity of the dehydration method while achieving superior results. By using controlled hydrolysis with specific water content (30-50% of soybean oil sediment weight) followed by centrifugal separation, the process replicates the ease of manufacture of conventional methods but produces phospholipids with acetone insoluble content of 95-98 g/100 g, eliminating the need for chemical bleaching
2Productivity
If conventional hydration method with insufficient water addition is used, then the process is efficient, but it is difficult to separate inactivated phospholipids and water-soluble impurities
Solution Approach 1:
The patent introduces centrifugal separation as an intermediary step between hydrolysis and product recovery. This centrifugal separation process effectively separates inactivated phospholipids and water-soluble impurities from active phospholipids, achieving high separation quality while maintaining processing efficiency. The method ensures the phospholipid product has acetone insoluble content of 95-98 g/100 g and maintains surface activity
Solution Approach 2:
The patent optimizes the water content parameter to 30-50% of soybean oil sediment weight, which is sufficient to enable complete hydrolysis and effective separation. This parameter change allows inactivated phospholipids and water-soluble impurities to be properly separated through centrifugation while maintaining high processing efficiency and producing phospholipids with acetone insoluble content of 95-98 g/100 g
3Shape
If chemical bleaching is used to improve phospholipid quality, then the appearance is improved, but the natural structure and antioxidant properties are damaged
Solution Approach 1:
The patent converts the harmful effect of chemical bleaching into a beneficial physical separation process. By using centrifugal separation based on density differences, the method naturally separates impurities and inactivated phospholipids from active phospholipids without chemical intervention. This produces phospholipids with improved appearance (acetone insoluble content of 95-98 g/100 g) while preserving natural structure and antioxidant properties
Solution Approach 2:
The patent enables the phospholipid system to self-separate impurities through centrifugal forces without external chemical agents. The density difference between active phospholipids and impurities allows automatic separation during centrifugation, achieving improved appearance quality while maintaining the natural structure and antioxidant properties of the phospholipids
